Hey Vinc360,
I am glad I checked the forum a couple of days ago and read your post because I actually received this notification last night. However, mine wasnt an email. It was written as such, but they actually printed it and sent it to me by mail (I am currently in Canada after applying from abroad). I think it's more of a reminder as we are approaching the final part of the application, especially the validity of the passport. I actually have done everything that is mentioned in the letter. Thanks to the forum, I didnt freak out
